ELECTRIC-LAMP HANGER.

Specification of Letters Patent.

Application filed May a, 1919, Serial no. 295,116. Renewed July 10,1920. Serial No. 395,333.

T all whom it may concern Beit known that I, NATHAN L. Conn, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Electric-Lamp Hangers; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to electric lamp hangers, and it relates morespecifically to an lIIIPI'OVBd canopy and its connecting elements.

One object of the invention is to generally improve upon, simplify andreduce the cost of devices of this character.

A further object is to provide an improved device of this characterwhich is exceedingly convenient and easy to attach to and detach from anordinary electric outlet connection. A still further object is toprovide a device of this character in which the canopy supports theelectric lamp, beingunited wit the chain or other connection whichcarries the lamp.

Other objects and advantages may become apparent to personswho read thefollowing details of description in connection with the accompanyingdrawings, in which:

Figure l is a central vertical sectional view through a deviceillustrating one our bodiment of my invention.

Fig, 2 is a perspective view illustrating a combined insulating andcanopy supporting element'of the invention.

Fig. 3 is a perspective view illustrating myimproved canopy, especiallythe struckup hook-engaging portions.

Fi 4 is a horizontal sectional view along the lines 44 of Fig. 1.

Referring to these drawings in detail, in which similar referencecharacters correspond with similar parts throughout the sleeve or nut 9which extends through the center of the insulating disk. It will be seenthat by tightening the nut 9, the upper margin or rim of the disk 8 ispressed against the ceiling and thereby held firmly in itscanopy-supporting position. The insulating disk 8 is formed with aperipheral shoulder 10 which provides a seat for the upper rim of thecanopy 7 and spaces the dome from the ceilin .The canopy 7 is formedwith loops or pockets 11 which are struck up from vertically defiectableportions of springy sheet metal of which the canopy is integrallyformed, and hooks 12 are normally engaged with or seated in the pockets11, the upper ends of the hooks 12' being 'adjustably sewhich theircenters are disposed; that is,

the centers of the hooks shanks coincide with a circle which isconcentric with the' periphery of the" disk 8, so that when the upperrim of the canopy is seated on the shoulder 10, thecanopy may be given arotary movement for engaging the hooks 12 with the loops or pockets 11,and by moving the canopy in the opposite direction, the hooks may bedisengaged from the loops or pockets. The adjustment of the hooks shouldbe such that the sheet metal adjacent to the loops 11 will exert aspring tension for holding the canopy in its useful position by itsfrictional engagement with the hooks and with theshoulder 10,andthisadjust: men-t may be made by means of nuts 13, so that canopies ofvarying dimensions ma be supported by the insulating disk 7 an itshooks. A loop-eye or other appropriate lamp-supporting connection-14 hasa screwthreaded upper end 15 which extends through an aperture in thelower end of the canopy and is secured in its supporting position bymeans of a nut 16 or other appropriate means. The upper portion of thesupporting connection 14 is tubular, beingpro I vided with awire-receiving bore or aperture 17 which is in open communication with:the interior and exterior of the canopy, so that the electric conductors18 may be passed through the lower central part of the canopy andelectrically connected, as at 19, with the terminals which extend downthrough the outlet box.

A chain or other lamp-supporting means 20 may either carry a lampsocket, or any appropriate electrical connection for a lamp or otherelectrically operated or controlled object.

From the foregoing, it will be seen that the canopy 7 and elementssupported thereby constitute the means for supporting the lamp or otherobject, in contradistinction to prior devices which require supportingmeans for the lamp in addition to the canopy for covering the outlet boxand connections. In other words, my improved device dispenses with theexpensive elements employed by previously known devices, and utilizesthe canopy for performing the dual function of supporting the lamp andcovering the outletconnections. Moreover, I employ an insulating disk 2%to perform the dual function of insulating the canopy from the ceilingand supporting the canopy.

From the foregoing description of the structure, arrangement, andfunctions, it will be seen that an electric fixture compris- 4 ing myinvention may be very quickly, easily and conveniently, removed from theceiling connection, and very quickly and easily transferred to anotherconnection or outlet is not intended to limitthe invention to theseexact details of construction and arrangement, but changes may be madewithin the scope of the inventive idea as described and claimed.

What I claim as my invention is:

1. In an electric fixture, a disk having a central opening to receivemeans for attaching it to a junction box, said disk having a hooksconstituting approximately horizontal elements which extend tangentiallyfrom a circle concentric with said central opening, these tangentiallyextending elements. of the hooks being seata'ble in and removable fromsaid pockets by rotary movements of the canoply.

2. he combination of an electric insulating disk adapted to be supportedat an elec tric wire outlet, a plurality of hooks secured to andsupported by said insulating disk, and a canopy comprising verticallydeflectable springy portions spaced from'the upper end of the canopy andprovided with a plurality of inwardly extending hook-engaging elementswhich are engageable with said hooks so as to support said canopy andyieldingly press itsupper end against said insulating disk, said canopybeing disengageable from said hooks by a horizontal relative movement ofthe hooks and canopy.

In testimony whereof I have hereunto set my hand.
